Graph.Coloring
k
-coloring of undirected graphs.
A k
-coloring of a graph g
is a mapping c
from nodes to \{1,...,k\}
such that c(u) <> c(v)
for any edge u-v
in g
.
Provide a function for k
-coloring a graph with integer marks. The provided function is more efficient that the one provided by functor Make
above.
